A friend of mine had a problem. With the upgrade to Ubuntu 10.04 his Logitech webcam didn’t work anymore with skype. The solution was a bit tricky, because he had all he need, means skype-wrapper was installed correctly.
In the end it came out, that the menu link was not correctly updated or set-up by the installer and tried to call skype directly instead of skype-wrapper. With my 64-bit version this worked out of the box, maybe it’s just a problem of the 32-bit version - but easy to fix. Just rename the calling command from skype to skype-wrapper. Thats all :-)
